Margaret Hutchinson Rousseau passed away on October 28, 2001, in Chestertown, Maryland, at the age of 90. Her death marked the end of a remarkable life that spanned some of the most transformative decades in the history of chemical engineering and industrial science.
Rousseau's legacy rests primarily on her wartime achievement designing the process engineering for the first commercial penicillin manufacturing plant for Merck & Co. during World War II, a contribution credited with helping make the life-saving antibiotic available on a mass scale to Allied forces and civilians. She was also celebrated as a trailblazer for women in engineering, having broken multiple barriers throughout her career, including her doctorate from MIT and her landmark election to the American Institute of Chemical Engineers.
In the years following her death, historians, engineering societies, and organizations dedicated to celebrating women in STEM have highlighted her story as an example of the crucial, if historically underrecognized, role women played in the development of wartime medicine and modern chemical engineering. Her life continues to be studied and celebrated in retrospectives on the history of antibiotics and women's contributions to science and engineering.
